Practical AI tip: When someone sends me a PDF calendar (😡), I ask Claude to process the info into ICS format. For my kids' daycare snack calendar, I say:

Please convert data from each day to one all-day event, like: Snacks: AM: Cheerios / PM: Crackers

And I get the excellent result pictured here.

A screenshot of Fantastical for iOS shows a calendar schedule of snacks for each day, including applesauce, nachos, granola bars, cucumbers, yogurt, and pretzels.
